guys, guys, Rangerovers only ever came in either 2 or 4 door as technically I suppose they don't have a single door as the tailgate as its split so thats the end of the door worries. To add to the floor worries I have 2 x 2 door rangie's a 78 and a 83, the 78 is a flat front to the rear seats and the 83 is a sloped one. I can see no reason as to why underneath so the question is still when did they change and for why. well the when is a matter for the anoraks out there bu the why MAY be that it is stronger to have a angle like that when forming the floor and uses less metal and is pressed easier so that may be why but we need to ask all those 2 door rangie to look as to what they have and let us know the year we may be able to find one with a slopy and one with a flat in the same year and we then have our timeframe. But to tell the truth i aint interested, it works and that's that. Simon
